: : I am planning on adding a shower stall to an upstair half bath. Even with shifting walls out & back various distances, I only have room for a 32" shower stall. I am told these are not legal in the U.S.,but may be available through a Canadian mfg. This is turning out to be a "covert" project! Any assistance appreciated; if a 32" is illegal, what is the rationale??: : (Showerless in MA)
